Okay, so we are going to draw parallel lines using the square set, yeah? 00:00:00
I remind you that those in English are called square templates, both of them. 00:00:05
There are no difference in the name of those two templates, but in Spanish, this one is the escuadra. 00:00:10
It's the one who has 45 degrees in each angle and 90 degrees in this one. 00:00:20
Those sides measure the same. 00:00:27
And this is the cartabón, okay? 00:00:30
The angles are 90 degrees, 60, and 30, yeah? 00:00:33
And the sides are different. 00:00:37
Okay, so usually we draw with the escuadra, yeah? 00:00:40
So we select the line that we want to copy, so to speak, okay? 00:00:46
We want to do parallel lines to another one. 00:00:52
So the first one is going to be the edge of the template, the box, the edge of the box, of this square. 00:00:55
And we put this line, this side of the triangle, it's called hypotenuse, it's the opposite to the 90 degrees to the right angle. 00:01:08
okay so we put it here yeah um and with the hand it's very important not to move it once you put 00:01:21
it don't move it okay don't don't don't leave it to to slide yeah okay so put here the 00:01:31
the the squadra and down below we put the cartabón yeah it's important to 00:01:39
put it together okay they have to touch not put one over the other one neither leaving space yeah 00:01:48
not any spaces they have to touch because they have to slide yeah one on each other 00:01:58
so once you have put the cardamom you 00:02:04
lift them, you have to take them. Okay, so now we're going to make parallel lines 00:02:07
following those directions, this direction. So I see there are 45 degrees, yeah? Where do we have 00:02:19
45 degrees? In the escuadra, okay? So what I'm going to do is to, here, I'm going to move a 00:02:28
little bit a little the camera okay I'm going to put this time I'm not going to 00:02:36
put the hypotenuse I'm going to put the catheters this one okay the other side 00:02:41
here yeah mm-hmm behind I'm going to put the cartabon yeah do you see here the 00:02:47
cartabon and oops I have moved the squadra so I have to do it with care 00:02:58
Okay, so behind I put the cartabon and now I can slide the escuadra following the lines. 00:03:05
I'm going to make a small trick, okay? 00:03:17
I'm going to make lines to the end here, okay? 00:03:19
Look at my fingers, yeah? 00:03:30
Start pressing the escuadra. 00:03:33
The cartabon doesn't move, the escuadra slides. 00:03:37
Okay, now I can't move my fingers more, so I'm going to take the, okay, it's very important that the cartagón doesn't move, okay, but you have to be not totally comfortable, but enough to continue doing it. 00:03:44
Now, as you see, here there are lines just in the opposite way. 00:04:13
So what I'm going to do, look, look, very important, I'm going to turn this cuadra. 00:04:23
Look over the 90 degrees angle, ta-ta-ta-ta-ta-ta, ta-m, ok? 00:04:28
I have turned it. 00:04:36
This is the way to draw perpendicular lines. 00:04:37
Now I'm drawing propelliculant lines to the previous one, do you see? 00:04:42
If I feel like the escuadra is going to fall down, I can move the cartabón, but without 00:04:58
of care, I go over the first line and pressing the escuadra, holding properly, I move the 00:05:05
cartabón. 00:05:13
Now I can continue. 00:05:14
Finish! 00:05:43
Well done! 00:05:44
Do you think you are able to do it also with the technical pen? 00:05:45
